我们希望按import java.util.Scanner; //Needed for Scanner class.
public class PayrollTest
{
public static void main(String[] args)
{
String EmployeeName;
int IDnumber;
double HoursWorked;
double HourlyPayRate;
double GrossPay;
//Create a Scanner object for keyboard input.
Scanner keyboard = new Scanner(System.in);
//Get the employee's name.
System.out.println("Enter an employee's name: ");
EmployeeName = keyboard.nextLine();
//Get the employee's ID.
System.out.println("Enter the employee's ID " );
IDnumber = keyboard.nextInt();
//Get the number of hours worked by the employee.
System.out.println("Enter the amount of hours worked by this employee: ");
HoursWorked = keyboard.nextDouble();
//Get the hourly pay rate of the employee.
System.out.println("Enter the hourly pay rate for this employee: ");
HourlyPayRate = keyboard.nextDouble();
//Create a payroll object, passing EmployeeName and IDnumber
// as arguments to the constructor.
Payroll pay = new Payroll(EmployeeName, IDnumber);
//Get the Gross Pay of the employee.
System.out.println("The gross pay of " + EmployeeName + " is: " + pay.getGrossPay());
}
}
代表：total- count
此外，我们希望按日期排序，以防在排序时有两个数字并列。
是否可以在Solr中执行此操作？
答案 0 :(得分：3)
是的，这是可能的。 Solr允许通过函数的输出对结果进行排序，因此您可以使用sub()从 total 中减去 count 。它还支持多种排序，您可以提供以逗号分隔的排序条件列表。
排序顺序必须包含字段名称（或分数为伪 字段），后跟空格（在URL字符串中转义为+或％20）， 然后是排序方向。
在您的情况下，您可以执行以下操作：
sort=sub(Total_ix, count_ix) desc, date desc
